So it's taken 3 months but the foundations are finally in!
The piling company came yesterday and put in the cages, which you can see below, which have anti-heave under them. It's basically glorified polystyrene. They then proceeded to fill all the trenches with concrete which set overnight.
We had to lock the cats in to make sure we didn't have half a kitty sticking out of wet cement.
Anyway, very happy to have that all out of the way, so onward and upward now with the build!
